The Miami Herald has obtained Parkland shooter Nikolas Cruz's school psychiatric file, and it contains disturbing details of his talks with mental health professionals. Nikolas Cruz, who has admitted to gunning down 17 at Florida's Marjory Stoneman Douglas High School last month, attended an alternative school before being mainstreamed into Stoneman Douglas; the Washington Post notes he had disciplinary issues at middle school and left in eighth grade.

Many of the files deal with his weekly meetings with his therapist at Cross Creek School, whose students have emotional or behavioral problems, from the time he was 15 to 17 years old.

In 2014, for example, he told that therapist he'd had a dream about killing people and being covered in blood; administrators, in response, came up with a "safety plan" for him over the summer that involved removing "all sharp objects from the home."

Cruz, formally charged last week with 17 counts of premeditated murder and 17 counts of attempted murder, also told his therapist he went on YouTube to "research wars, military material, and terrorist topics," and he wrote a paper about his fantasy of a "perfect summer" that would involve him buying a gun and target-shooting until he got bored or ran out of ammo.

The therapist and school psychiatrist describe troubling behavior from Cruz in the files, including aggressive and destructive behavior at home, threatening behavior at school, an obsession with guns and the military, and paranoia.

The school therapist advised against Cruz being given the pellet gun he desired, and it was recommended he not be allowed to become an ROTC cadet.

Toward the end of the file, "tremendous progress" is noted, and he was allowed to move to Stoneman Douglas by January 2016. See the Herald for more.
